Donald Osmund Oslear (3 March 1929 – 10 May 2018) was a Test cricket umpire from England.

He stood in five Test matches between 1980 and 1984 and eight One Day Internationals, including a semi-final of the 1983 World Cup.

[2] Alongside John Holder, he is credited with the idea of a 'bowl-out' to decide a drawn match after the 55-over 1987 Tilcon Trophy final had been washed out by rain.

The organisers had ordered them to think of another way of settling the match rather than the traditional and sometimes unpopular means of the toss of a coin.
